.A 4The present invention relates to an attaching device adapted to be used 'for various attachment purposes. It may, for instance, be.

employed advantageously in conjunction a with an anti-splashing device or mud guard,

in whichan angular strip .o't' elastic material, such as rubber', is secured to one or to either side of a wheel tire by means ot' radial arms orother connecting members, which are coni nected to one or more metal supporting rings..

'lhe attachment serves in this instance for connecting the above mentioned radial arms or other members with thewheel.`

kThe attachment embodying vthe invention consists in the first place of a casing into which one or mor-e zigzag-shaped or corrugated tongues enter,`which tongues, outside lthe casing, are adapted to be connected with one or more parts to be attached, and inside the casing are clamped or locked in position by means of one or nioreclamping elements.

Various constructions based on this principle-are possible. According tothe invention the casing itselil may, t'or` example, be provided with the zigzag-shaped or corrugated central member, againstvopposite sides of which are arranged two correspondingly zigzag-shaped or corrugated tongues, while` within the casing means are provided for clamping the two tongues against the central member.

Instead of this duplex arrrangement having two tongues and a cental member, an embodiment may also be used in which only one zigzag-shaped or corrugated tongue enters into the casing and is clamped against the correspondingly zigzag-shaped or corrugated inner side of a wall of the casing.

Furthermore, according to the invention the clamping members may consist of one or- `more rollers, which are each rotatable about an eccentric axis and which may be vflattened, the axis of rotation of the said rollers being parallel to the longitudinal direction of the tongues. lThe rollers may also be self-locking. According as the double or single tongue construction is used, a pair of` clamping rollers or a single clamping roller will be employed.

The invention will be more fully understood with reference to the accompanying drawings illustrating it by way ofexample.

Fig. 1 .shows a radial section of a portion ola motor car wheel to which, by means of an attachment according to the invention,

right-hand metal strip 4' is connected,

lateril angular mud-strips or guards'are 'secure i .Figf2 is a section on the line II-IIiin F1g. 1,. `f Y Fi 3 is a section of a modicationof the points between two spokes.attaching-devices v or connecting-units are arrang`ed,adapted to connect to the wheel angular metal strips4 ypro-vided with radial arms 5, carrying Vat their outer ends angular rubber mudguards or strips 6. lEach attachingdevicelor unit comprises a casinor 7, provided with a stationary corrugated central portion or tongue `8. The corrugated upper sldeoi:l this tongue is engaged by a correspondingly corrugated tongue 9, to which, outside 'the casing, the while the corrugated lower side of the central tongue 1s engaged by a'correspondingly corrugated tongue V10 on theA left-hand metal strip 4. The. tongues 9andv10y mayL enter into the casing throu h openings" 11 and 12 respectively, provide in the side walls of the oasmg. Each tongue 9 and 10 may be clamped a ainst the central tongue 8 in the position s own by means of an eccentric The casings or rings aresuitably connected to the wheel, as'by means of boltspassing through the rings 4, while' between the spokes and the rings filling piecesr or the like of rubber may be arranged.-

In the Vembodiment according to Fig. 3 the casing 7 of Figs. 1 and 2 is practically vdivided into equal halves and the corrugated inner side of the lower wall 15 of the casing is engaged by a' correspondinglyv corrugated tongue 9 of a single ring 4, located at one i i vside of the wheel. Y

It will be clear that the tongues 9 Vand 10 need not be connected to or made integral with the rings 4. They may also be connected to the radial arms 5 or be made integral with ltihese arms. In general the tongues and the casing may be connected to aribtrary parts to be attached to each other.

I claim:

1. An attaching device, comprisingl a casing, a corrugated central member disposed Within and secured to the casing, a corre s'ondngly corrugated tongue entering into tiie casing and bearing against one side of the central member, a correspondingly cor rugated tongue entering into the casing and bearing against the other side oi the central member, and means Within the casing t'or clamping the tWo tongues against the cen'- tralV member.

2. An attaching device, comprising'a' casing provided with a corrugated internal surface, an attaching member external to the casing; a tongue rigidly connected to said. member and extending into said casing, said tongue having'corrugations corresponding to those of said surface to interfit With the'same; and means Within the casing for clamping said tongue against said surface. 3. An attaching device, comprising a casing provided with a corrugated internal surface; an attaching member external to the casing; a tongue rigidly connected to said member and extending into said casing, said tongue having corrugations corresponding to those of said surface to intertit with the same; and an eccentrically mounted roller Within the casing or' clamping said tongue against said surface. Y 4. An attaching device, according to claim 3, in which the axis ofthe clamping roller a lateral tongue rigidly secured to said member Vand projecting into the casing; a me1n ber disposed within and'rigidly connected to said casing and with which said tongue is directlyl engaged; and an eccentrically mounted clamping roller within the casing i'or holding said tongue and last-named member in engagement.

7. 'An attaching device, comprising a casing; a member disposed centrally Within and rigidly attached to the casing; attaching members external'to said casing and Vdisposed at opposite sides thereof; a pair of l al tongues connected to the attaching members and extending into the casing at opposite sides oi said central member, said tongues and central member having interengaging parte; and means Within the casing for clamping the tongues and central meubel' together With their aforesaid parts in interengaged relation.

in testimony whereof I aIiX my signature.`
